Abstract: PURPOSE:To largely reduce the stress of a casing and the pass resistance of a valve by maintaining the inside and outside diameters of a upper chamber being the maximum diameter of a casing body as they are up to the midway of a lower chamber and forming the remaining parts of the chamber in a spherical band shape. CONSTITUTION:As to the outside shape of a valve casing, the cylindrical shape of the upper chamber 15 of a casing body 9 is maintained as it is to the lower side and formed in a spherical band shape on the way of a lower chamber 13, and as to the inside, the lower chamber 13 takes such a shape as obtained by laying one spherical band on the top of another one. Accordingly, it is possible to widen an interval between steam passes 14 and it is not required to allow a steam outlet pipe 11 and a uniform pressure tube 12 to deviate from the center of a body 9. And, it is prevented that any excessive force is applied to a casing supporting mechanism, with the good balancing of the valve casing. Moreover, it is possible to reduce the whole stress values of the chamber 13 because of the widened interval between the passes 14, and reduce flow passage loss because the steam passing through between the valve body 18 and the valve seat 19 does not hit the side wall of the chamber 13 at an acute angle.

Title: Speed controller for car
Inventor: TANIGAWA MITSUARI
IPC: G05D13/62
Filed: 1981-05-27
Abstract: PURPOSE:To increase comfortable riding characteristics on an ascending road with simple constitution, by delaying the restart of overdriving for a period equivalent to the set time of a timer after the traveling speed of a car is reset to the set value. CONSTITUTION:The fact that the traveling speed of a car increases up to about set value is detected by a cmparator 110 which compares the reference voltage 112 with the voltage (c) coresponding to an erroneous speed. Then a timer 114 is set by the output of the comparator 110. As a result, an FF113 is reset when a prescribed period of time elapses, and an overdrive cutting coil 117 is turned off to restart the overdriving. As a result, the deterioration caused in comfortable riding by the frequent change of the traveling speed of the car can be avoided. The timer 114 is reset by the output of an inverter 115 when the traveling speed of the car is reduced down to a level almost equal to the set traveling speed.
